Use the Override pick action to temporarily override a point’s value. You might want to use this action, for example, to specify a suitable value if Geo SCADA Expert has detected a known fault that is causing an incorrect value to be reported. Once the detected fault has been corrected, use the Release Override action to revert back to using the point’s actual value—the value that is being reported by the outstation or scanner.
